This invention relates to improvements in plumbing connections, andparticularly to connections leading from toilet bowls.

In supplying various plumbing fixtures to a building it frequentlyoccurs that the finished floor level or the finished side of a wallvaries in position from that which was originally contemplated in theplans of the building. When this variation occurs between the actualfinished floor level. or the side of a wall, changes are required in theplumbing. This is particularly true in properly positioning a toiletbowl in a building.

An object of this invention is to provide an improved construction forconveying the refuse from a toilet bowl to a soil pipe which permits anadjustment of the toilet bowl so that it may be properly positioned withrespect to the finished fioor level or the finished side of a wall,which may vary from that originally planned.

A further object of the invention is to provide an improved constructionfor what is commonly known in the trade as a cast iron closet bend.

Another object of the invention is to provide an improved constructionfor connecting a closet bend to the toilet bowl which permits adjustmentof the bowl relatively to the bend, and at the same time affords a ointwhich is rigid and strong and which is gas proof against the escape ofsewer gas.

Another object of the invention is to provide a calking ring or what isgenerally known to the trade as a closet ring which forms the connectionbetween the closet bend and the outlet from the toilet bowl.

lVith the foregoing and other objects in view, which will be mademanifest in the following detailed description and specifically pointedout in the appended claims, reference is had to the accompanyingdrawings foran illustrative embodiment of the invention herein.

Referring to the accompanying drawings wherein similar referencecharacters designate similar parts throughout, the floor or the buildingin its finished condition is indicated 7 at F and in a similar manner afinished wall is indicated W. In order to fully appreciate theadvantages of the invention, brief er;-

planation of prior methods of installing toilet bowls in buildings isbelieved to be required. Heretofore it has been customary to employ acloset bend which is in the form of an elbow and which is connecteddirectly to a soil pipe. One branch of the elbow is caused to extendupwardly throu upper end terminate some distance above what is estimatedwill be the finished floor level. The upper end 01 this branch is thencut off if it is too high so that its upper end will be approximatelyeven with what is esti mated will be the finished fioor level. A calkingring or closet ring is then caused to be positioned over the upper endof this branch of the closet bend and is fastened thereto by pouringcalliing lead the ring 95 and calking it by means ol a calking tool.This ring is positioned upon the outside of the closet bend. The closetbend employed has a diameter which is the same throughout its entirelength and which is equal to the @423 the floor and to have its diameterof the outlet from the toilet bowl. Consequently it it should happenthat the finished floor level is raised above that originally planned,and this not infrequently occurs, the ring too low for attachment to thetoilet bowl causing a considerable amount of expense and labor tomake'the corrections in the plumb? It also sometimes happens that thelinis ed sr face of t is wall is moved further toward the center of theroom than originally contemplated. This may require that the toilet bowlbe shifted farther to var-d the cent-er of the room so that its out-letis no longer in alignment with the up-standing branch of the closetbend, causing expense and labor to make the correction.

The improved construction is designed to eliminate these diiiiculties.In the modification shown in Fig. 1 there is a closet bend in the formof an elbow. Such closet bend can be formed of cast iron or anyequivalent material, and it is so formed that its upstanding branch 11is somewhat greater in diameter than the horizontal branch 12 which isadapted to be connected to the soil pipe, not shown. The horizontalbranch 12 .has substantially the same diameter as the outlet 13 from thetoilet bowl T, the conventional diameter employed for these parts beingfour inches. It the diameter of the horizontal branch 12 and the outlet18 is four inches, the tip-standing branch 11 is j'iret'erably made witha diameter of about 6% inches, although it will be understood that theactual dimensions may vary.

The closet bend 10 is first installed in the building and has itsrip-standing branch 11 extending upward some distance so that it willproject a short distance above what is contemplated as being thefinished floor level. The closet bend or elbow 10 is allowed to remainin this condition until the finished floor F is laid and also thefinished wall N is constructed. At that time the surplus or projectingportion of the lip-standing branch 11 cut oil so that the top edge ofthe branch 11 is substantially flush with the floor F. T .is branch maybe cut oil in any suitable manner such with a cold chisel.

A calking or closet ring 14 is then positioned within the upper end or"the l. 'anch 11, such rin g having an aperture 15 formed therethrough,and havi g a flange 16 located in a plane below the body of the ring andconnected thereto by an annular apron 16 depending from the outercircumference of the ring. This flange. together with the body of thering, cooperates with the interior surface of the branch 11 to form agroove 1'? within aperture 15. On the under side of the conventionaltoilet bowl there is a recess 18. This recess is of such size that itwill completely cover and receive the upper end of the branch 11 eventhough it has its diameter increased. llithin this recess there isplaced putty, wax, or other material, and the bowl is lowered intoplace. On the ring 14 on diametrically opposite sides of the aperture 15there are ears 19 having threaded apertures which receive the lower endsof bolts 20 through the base of the toilet bowlT. The ears 19 arelocated otherwise than on diameters of the ring 14 and aperture 15 whichcoincide and they are preterably arranged transversely of the coincidentdiameters of the ring and aperture. In this manner the toilet bowl isfirmly and rigidly fastened to the branch 11 of the closet bend or elbow10. The calked joint, together with the putty or wax, forms a tightgasproof joint which is equally as strong as the joint heretoforeprovided in this connection.

From the above described method of installing the connect-ion, it willbe appreciated that it is always possible, with the improvedconstruction, to have the upper end of the elbow 1O practically evenwith the finished floor level so that the bowl will rest evenly on thefloor and so that the upper end of the branch 11 is sufliciently closeto the outlet 13 to form the desired joint.

The improved joint also provides for adjustment of the bowl relativelyto the bend or elbow 10. From an inspection of Figs. 3, 4 and 5, it willbe noted that the center of the aperture 15 is otherwise than coincidentwith the center of the ring 14. If the ring 14 is placed in the positionshown in Figs. 1 and 3, the aperture 15 will be so positioned that thebowl T is in its rear-most position with respect to the elbow or bend10, which cannot be changed after it has been once installed.

If it should so happen that the finished wall surface should vary and bemoved toward the center of the room from the position origi nallycontemplated, the ring 14 can be reversed from the position shown inFig. 3 into the position shown in Fig. 4. In such position it will benoted that the center of the aperture 15 is moved on the far side of thecenter of the branch 11 from the wall IV. Consequently when the outlet13 is positioned in the aperture, the toilet bowl T will be caused toa."-

sume a position more toward the right from the position shown in Fig. 1,thus accommodating the change in the position of the linished wallsurface withoutrequiring achange in the connecting pipe 21 which leadsfrom the supply tank 22.

In this manner a single ring 14 provides "for adjustment of the toiletbowl T, enabling the bowl to be positioned-in either of 'wo positionswith respect to the stationary elbow or bend 10. Various sizes of ringscan be provided in which the distance between the centers of theaperture 15 and of the ring 14 are varied, such as for example rings maybe provided where the distance between the centers is inch, inch, or Aof an inch. In this manner by arranging the aperture 15 eccentricallywith respect to the peripheral center of the ring 1 a. horizontaladjustment of the toilet bowl T with respect to the bend is pos sible.

It will be appreciated that the improved closet bend or elbow 10 can beconstructed in either of several difierent manners,'s0me of which areshown in Figs. 6, 7 and 8. The essential characteristic of all forms ofthe bend is that the rip-standing branch has a diameter considerablylarger than the diameter of the outlet 13 so as to accommodate the ring14: which is positioned within it, and which has its eccentricallyarranged aperture 15.

In the modification shown in Fig. 6 there is an rip-standing section oflarge pipe 23 forming the rip-standing branch and this section of pipehas its lower end reduced as at 24 and threaded into an elbow 25connecting it to the pipe 26 which leads to the soil pipe. In thismodification there are shown rooves 27 about the upper end of the pipe93 which facilitate cutting off the upper end of the pipe even with thefinished floor level. The same construction can be employed on anymodification of the closet bend.

In the modification shown in Fig. 7 there is an rip-standing pipesection 28 of large diameter which has its lower end reduced and 0formed into a bend, as indicated at 29, adapt ed to be connected to apipe 30 which leads to the soi pipe.

In 8 there is illustrated a section of pipe having the required largediameter, the pipe being indicated at 31, having a reduced lower end 39.which is adapted to be connect d by means of a call-zed joint to a pipelea o the soil pipe.

;v of the modifications it is not necessary that i119 horizontal branch12 of the closet bend be arranged perpendicularly to the plane of thewall IV. It will be understood that this branch may be arranged at anyangle with respect to the wall and that the ring ll can be positioned inthe upstanding branch ii and have the same advantages as when the branch12 is perpendicular to the wall IV.

From the above d scribed construction it will be appreciated that anovel toilet connection is provided which has numerous advantages inthat an adjustment is provided for the toilet bowl to accommodatechanges in the finished floor and wall surfaces of the building.Furthermore the improved connection can be easily and quickly assembledand also inspected.

It also has all of the advantages of joints 7 or connections heretoforeprovided for the same purpose.

Various changes may be made in the details of construction withoutdeparting from the spirit or scope of the invention as defined by theappended claims.
